Ross says that people on the inside of the Pentagon are telling him that the excuse given is that the Pentagon is protecting the national security value of technology derived from "vehicles" recovered.
But Ross said that he increasingly concludes that what is happening is that a small group inside the military-industrial complex is trying to protect itself from embarrassment and possible criminal retribution by the American public because of their covert operations/actions re: this matter.
For Ross this has been a teaching moment. My message to him:
Welcome to the Party, Ross.
Some folks figured this out seven decades ago.
Lol.
